2. The index was launched on November 18, 2009 and is sponsored by Standard and Poors Financial Services LLC.

3. Tracking error refers to the under/over performance differential of the indicative value of an ETN versus
its benchmark index over a given time period, after accounting for the ETNs fees and costs. One cannot invest directly in an index.

4. The investor fee is calculated on a daily basis in the following manner: The investor fee on the initial valuation date will be equal zero. On each subsequent calendar day until
maturity or early redemption, the investor fee will increase by an amount equal to 0.95% times the closing indicative note value of your securities on the immediately preceding calendar day times the closing level of the VEQTOR Index on such
calendar day divided by the closing level of the VEQTOR Index on the immediately preceding calendar day (or, if such day is not an index business day, the such quotient will equal one) divided by 365. Because your notes are subject to an
investor fee, the return on the VEQTOR ETNs will always be lower than the total return on a direct investment in the VEQTOR Index.

The majority of the notional value of the VEQTOR Index is usually allocated to the S&P 500® Total Return
Index, a broad representation of the largest market cap stocks listed in the United States.

Implied Volatility

The VEQTOR index seeks to provide a volatility hedge by dynamically allocating part of the
notional value to the S&P 500 VIX Short-Term FuturesTM Total Return Index.

Cash

The VEQTOR index includes a stop loss mechanism that shifts the entire notional investment to an
interest-bearing cash investment if the performance of the previous 5 business days fall by 2% or more.

IMPLIED VOLATILITY is a market estimate of the volatility an asset will realize over a future period of time, calculated
by reference to the market price of listed options on the asset.

Index Methodology Overview

(See appendix for more details)

In the attempt to
anticipate changes in the volatility environment, two signals are monitored on a daily basis:

1. Annualized
1-month Realized Volatility of the S&P 500® Index

2. Trend of the Implied Volatility (calculated by
reference to 5-day and 20-day moving average of the VIX® Index)

Based on the above signals, the index
dynamically allocates to notional equity and volatility exposure, seeking to provide:

Lower volatility
exposure during low or decreasing volatility periods

Higher volatility exposure during high or increasing
volatility periods

Stop loss mechanism:

 On any day, if the Index level has fallen by 2% or more over the previous 5 business days, the entire notional
value of the index is shifted to a Interest-bearing cash investment at the close of the following business day.

REALIZED VOLATILITY is an historical calculation of the degree of movement of an asset based
on prices or values of the asset itself, observed periodically in the market over a specific period.

IMPLIED
VOLATILITY is a market estimate of the volatility an asset will realize over a future period of time, calculated by reference to the market price of listed options on the asset.

Hypothetical Historical and Historical Index Performance ETN +

The following chart represents the hypothetical historical performance of the VEQTORTM Index since March 2006 (right
axis), together with the hypothetical percentage allocation to equity, volatility and cash (left axis).

Index returns are for illustrative purposes only. Index performance returns do not reflect any investor fees, transactions costs and expenses. Indexes are unmanaged and one cannot invest
directly in an Index. Past performance is not indicative of future results.

The S&P 500® Dynamic VEQTORTM Index was launched in November 2009. The information prior to launch dates included
above is hypothetical historical. You should not rely on historical or hypothetical historical information. Such historical and hypothetical historical information is not indicative of future performance.

1. Annualized Return is calculated as (1) one plus cumulative return of the power of (2) one divided by the
number of years in the observation period, minus (3) one

2. Annualized Volatility is calculated as a
standard deviation of natural logarithm daily returns in the observation period multiplied by the square root of 252. Because the annualized volatility is based on historical data, it may not predict variability on annualized future performance.

3. Correlation is the term used to describe the historical statistical relationship between two or more
quantities or variables. Perfectly correlated assets have a correlation coefficient of one, while the correlation coefficient is zero when returns on two assets are completely independent.

At the close of each business day, based on the realized volatility
environment and the implied volatility trend, the weightings of each of the equity and volatility components for the following days are allocated as follows:

Assuming no
stop loss event has occurred, volatility and equity component weights make up 100% of the notional index value

Index Calculationsstep IV

ETN +

Step IV: Stop loss feature

On each business day, the performance of the S&P 500® Dynamic VEQTORTM Index Excess Return over the previous 5
business days is evaluated.

If the 5-day performance is less than or equal to a fall of 2.0%, the Index will
allocate 100% of its notional value to cash position

Weights of both equity and volatility components are
zero.

Once the 5-day performance is greater than -2.0%, the index will allocate back to equity and volatility
components in accordance with the previous steps described.

Assuming the price and shape of the futures curve remain constant and a long position in a futures contract is
rolled:

 In backwardation, a more expensive contract will be sold and a cheaper contract purchased,
creating a roll yield, which can positively impact a long position in a futures contract

 In
contango, a cheaper contract will be sold and a more expensive contract purchased, creating a roll cost, which can negatively impact a long position in a futures contract

The S&P 500® Dynamic VEQTORTM Index was launched in November 2009. The information prior to launch dates included

IMPORTANT INFORMATION: Selected Risk Considerations

An investment in the ETNs involves risks. Selected risks are summarized here, but we urge you to read the more detailed
explanation of risks described under Risk Factors in the applicable prospectus supplement and pricing supplement.

You May Lose Some or All of Your Principal: The ETNs are exposed to any change in the level of the Index caused by any daily increase or decrease in the level of the Index. Additionally,
if the level of the Index is insufficient to offset the negative effect of the investor fee, you will lose some or all of your investment at maturity or upon redemption, even if the value of the Index has increased. The ETNs are riskier than
ordinary unsecured debt securities and have no principal prote

Dynamic Allocation Risk: The value of the Index
will depend upon the success of the Index in dynamically allocating between the equity and volatility components. The allocation of the Index to the equity and volatility components is based on realized volatility and implied volatility measurements
that may not effectively predict trends in future volatility, and is made in accordance with pre-defined weightings that may not be optimal.

The Stop Loss Feature of the Index Does Not Ensure That Losses Are Limited to 2%: The stop loss feature is designed to mitigate against losses in the Index by moving the Index into a 100%
cash position if the S&P 500® Dynamic VEQTOR Excess Return Index has lost 2% or more of its value over any five consecutive index business day period. Because the value of the Index may, for instance, decline more than 2% over a five
consecutive business day period prior to the occurrence of the stop loss event, decline more than 2% over longer than five consecutive business days, or decline over multiple stop loss events, the stop loss feature of the Index does not ensure that
losses are limited to 2%.

The Performance of the Underlying Indices are Unpredictable: An investment in the
ETNs linked to the performance of the Index is subject to risks associated with fluctuations, particularly a decline, in the performance of the Index. Because the performance of the Index is linked to the S&P 500® Total Return Index and the
S&P 500 VIX Short-Term FuturesTM Index TR (which seeks to model the return from a daily rolling long position in the first and second month CBOE Volatility Index® (the VIX Index) futures contracts) the performance of the Index
will depend on many factors including, the level of the S&P 500® Index, the prices of options on the S&P 500® Index, and the level of the VIX Index, which may change unpredictably, affecting the value of futures contracts on the VIX
Index and, consequently, the level of the Index. Additional factors that may contribute to fluctuations in the level of the Index include prevailing market prices and forward volatility levels of the U.S. stock markets and the equity securities
included in the S&P 500® Index, the prevailing market prices of options on the VIX Index, relevant futures contracts on the VIX Index, or any other financial instruments related to the S&P 500® Index and the VIX Index, interest
rates, supply and demand in the listed and over-the-counter equity derivative markets as well as hedging activities in the equity-linked structured product markets.

Market and Volatility Risk: The market value of the ETNs may be influenced by many unpredictable factors and may fluctuate between the date you purchase them and the maturity date or
redemption date. You may also sustain a significant loss if you sell your ETNs in the secondary market. Factors that may influence the market value of the ETNs include prevailing market prices of the U.S. stock markets, the index components included
in the Index, and prevailing market prices of options on the Index or any other financial instruments related to the Index; supply and demand for the ETNs, including inventory positions with Barclays Capital Inc. or any market maker; the time
remaining to the maturity of the ETNs; interest rates; or economic, financial, political, regulatory, geographical or judicial events that affect the level of the underlying Index or other financial instruments related to the Index. These factors
interrelate in complex ways, and the effect of one factor on the market value of your ETNs may offset or enhance the effect of another factor.
